GE DS200TCEAG1A Emergency Overspeed Board

Overview

The GE DS200TCEAG1A is an Emergency Overspeed Board for the GE Mark V Turbine Control System. It monitors turbine speed and detects flame conditions. The board protects turbines by sending emergency trip signals during overspeed events. It uses a microprocessor for high-speed control and processes various input signals. The board interfaces with other system components via IONET. It plays a critical role in ensuring turbine safety and reliability.
